No, Captain America cannot lean back and hold a helicopter that is lifting off. It doesn't matter how strong he is - he will be lifted once there is enough force generated from the propellers. Basically anything Batman does that involves gravity in the Nolan films is similar.
The magic I can get behind. The mutant stuff or dragons or even time travel in superhero movies doesn't bother me. It's the lack of sensible mechanics on an alleged Earth that I'm bothered by.
Yes! This seems like the right movie. For a few seconds before he grabs the pole, he does just lean back, right? That is the part that concerns me the most. At least this in the image seems doable if somebody is cap strong and angry.
I get your point, but I will say the Captain America scene isn't completely out of the realm of possibility. Cap weighs the helicopter down for a few seconds, and grabs a support beam for the helipad as soon as he can. If Cap can keep a grip on both the beam and the helicopter, then the propellers will only lift him if either Cap or the support beams break.
Of course, whether he should have had that much effect on the helicopter for those first few seconds is another matter entirely and I'm not enough of a physicist to make that call.

He isn't heavy enough to make that much of a difference before he grabs the ledge, is he? If the helicopter can manage lift, his 200 lbs shouldn't make that much difference. It's the part before he grabs the ledge that bothers me in this clip
